This is a very beginner question. And below is an arbitrary made up example:
Imagine you established communication with a USB device through your PC's USB COM port.
The USB device is measuring the voltage through it's analog input and then converting it to digital by its ADC. And through its port sending the 10-bit serial data to the PC through the USB cable.
Now the device has a sampling rate of 1kHz, i.e it takes 1000 samples of voltage per second.
And when I set the baud rates and the rest by using HyperTerminal and connect to the port, I can see 4 voltage readings per second as incoming lines.
My questions are:
1-) The analog sampling rate of the device was 1kHz, but I receive 4Hz per second. Does that mean the data is averaged? So does each received line in PC correspond to the average of 1000/4 = 250 samples' average?
2-) What is the 4 samples per second received by the PC called in literature? In data-sheets I cannot see a term called "output rate".
